Children who are inattentive have a hard time keeping their minds on any one thing and may get bored with a task after only a few minutes. If they are doing something they really enjoy, they have no trouble paying attention. But focusing deliberate, conscious attention to organizing and completing a task or learning something new is difficult.
Homework is particularly hard for these children. They will forget to write down an assignment, or leave it at school. They will forget to bring a book home, or bring the wrong one. The homework, if finally finished, is full of errors and erasures. Homework is often accompanied by frustration for both parent and child.
The DSM-IV-TR gives these signs of inattention:
Children diagnosed with the Predominantly Inattentive Type of ADHD are seldom impulsive or hyperactive, yet they have significant problems paying attention. They appear to be daydreaming, “spacey,” easily confused, slow moving, and lethargic. They may have difficulty processing information as quickly and accurately as other children. When the teacher gives oral or even written instructions, this child has a hard time understanding what he or she is supposed to do and makes frequent mistakes. Yet the child may sit quietly, unobtrusively, and even appear to be working but not fully attending to or understanding the task and the instructions.
These children don’t show significant problems with impulsivity and overactivity in the classroom, on the school ground, or at home. They may get along better with other children than the more impulsive and hyperactive types of ADHD, and they may not have the same sorts of social problems so common with the combined type of ADHD. So often their problems with inattention are overlooked. But they need help just as much as children with other types of ADHD, who cause more obvious problems in the classroom.
Whatever the specialist’s expertise, his or her first task is to gather information that will rule out other possible reasons for the child’s behavior. Among possible causes of ADHD-like behavior are the following:
Ideally, in ruling out other causes, the specialist checks the child’s school and medical records. There may be a school record of hearing or vision problems, since most schools automatically screen for these. The specialist tries to determine whether the home and classroom environments are unusually stressful or chaotic, and how the child’s parents and teachers deal with the child.
Next the specialist gathers information on the child’s ongoing behavior in order to compare these behaviors to the symptoms and diagnostic criteria listed in the DSM-IV-TR. This also involves talking with the child and, if possible, observing the child in class and other settings.
The child’s teachers, past and present, are asked to rate their observations of the child’s behavior on standardized evaluation forms, known as behavior rating scales, to compare the child’s behavior to that of other children the same age. While rating scales might seem overly subjective, teachers often get to know so many children that their judgment of how a child compares to others is usually a reliable and valid measure.
The specialist interviews the child’s teachers and parents, and may contact other people who know the child well, such as coaches or baby-sitters. Parents are asked to describe their child’s behavior in a variety of situations. They may also fill out a rating scale to indicate how severe and frequent the behaviors seem to be.
In most cases, the child will be evaluated for social adjustment and mental health. Tests of intelligence and learning achievement may be given to see if the child has a learning disability and whether the disability is in one or more subjects.
In looking at the results of these various sources of information, the specialist pays special attention to the child’s behavior during situations that are the most demanding of self-control, as well as noisy or unstructured situations such as parties, or during tasks that require sustained attention, like reading, working math problems, or playing a board game. Behavior during free play or while getting individual attention is given less importance in the evaluation. In such situations, most children with ADHD are able to control their behavior and perform better than in more restrictive situations.
The specialist then pieces together a profile of the child’s behavior. Which ADHD-like behaviors listed in the most recent DSM does the child show? How often? In what situations? How long has the child been doing them? How old was the child when the problem started? Are the behavior problems relatively chronic or enduring or are they periodic in nature? Are the behaviors seriously interfering with the child’s friendships, school activities, home life, or participation in community activities? Does the child have any other related problems? The answers to these questions help identify whether the child’s hyperactivity, impulsivity, and inattention are significant and long-standing. If so, the child may be diagnosed with ADHD.
A correct diagnosis often resolves confusion about the reasons for the child’s problems that lets parents and child move forward in their lives with more accurate information on what is wrong and what can be done to help. Once the disorder is diagnosed, the child and family can begin to receive whatever combination of educational, medical, and emotional help they need. This may include providing recommendations to school staff, seeking out a more appropriate classroom setting, selecting the right medication, and helping parents to manage their child’s behavior.
